Treatment of Renal Colic When Kidney Stone Is Larger Than 10 mm or Significant Hydronephrosis Is Present

Clinical Scenario

This protocol applies to patients presenting with renal colic where imaging demonstrates a kidney stone exceeding 10 mm in size, or where significant hydronephrosis (dilation of the renal pelvis) is identified. These findings place the patient outside the typical expectant management pathway.

Key Conditions

Either a stone size larger than 10 mm or the presence of significant hydronephrosis indicates that standard conservative measures are insufficient, and an escalated, specialist-directed approach is required.

Treatment Approach (Overview)

The protocol involves prompt pain relief using an anti-inflammatory analgesic, alongside a defined pathway for active stone removal — which specific steps follow, and when, is covered in full in the structured protocol below.

Clinical Goal

Kidney stone removal confirmed on imaging.

References

Referral to a urologist for active stone removal is warranted when the stone is larger than 10 mm or if significant hydronephrosis is present.

Nonsteroidal anti-inflammatory drugs (e.g., ketorolac, 30 to 60 mg intramuscularly) are more effective and have fewer adverse effects than opioids.
